To guarantee access, the following steps should be taken:

• Enable the "Global Mode" setting found in the routing options.
• Adjust the proxy settings of the application. For instance, here's how to change the proxy settings for the LINE app:

We have observed that some users find it challenging to select a server after choosing a region.

To make this easier, we now only show regions. Heibao will automatically connect you to the server that performs the best within your selected region. Here are the details:

• The location menu will only present regions, but each region includes hundreds of servers. When you pick a region, Heibao will automatically connect you to the server that delivers the optimal performance based on your network conditions.
• If you are not happy with the server to which you are connected, you can disconnect and reconnect to the same region to be assigned to a different server.
• You can repeat this process until you discover a server that fulfills your requirements.

Frequently encountered reasons for network problems are:

• Local slow internet speeds (without utilizing a NPV)
• Increased user traffic at specific NPV server locations

To address these problems, you might consider the following approaches:

• Verify your local internet speed by temporarily disabling the NPV
• Experiment with various network connections such as WiFi, 4G, or 5G with the NPV turned off to detect any connection issues. For instance, if your WiFi is inconsistent, switch to a mobile data connection.
• Disable the NPV, select a new server location, and then reconnect
• If you prefer to maintain a connection to the same geographical area, disconnect and reconnect as this might connect you to a different server within the same region.
• Keep conducting these tests until you identify the best server that meets your needs.

Global Mode: Activating this option enables NPV for all online activities, which could lead to slower performance for local websites and applications.

Split Mode: This option applies NPV solely to sites that are restricted based on geographic location, like Google, YouTube, and Netflix, while ensuring local network access remains available for Chinese websites.

You can modify the routing mode in the App Settings.

If you experience difficulties accessing specific websites or applications, consider switching to "Global Mode."
